In Python, there are many built in functions that are used in lists. They range from repeating an iteration of a list to giving the total length of one. Here are a couple of examples of the functions that you may run into when using lists.

With the Len method, the length of a list is returned

The syntax is len(list)

The append method passes a string into a list, when the function is called.

The syntax is list.append(object)

The index method returns the index of the listed object in the given list.

The syntax is list.index(object)

The reverse method returns the list, but in reversed form.

The syntax is list.reverse()

​​

The remove method removes an item or object from the list and returns the newly updated version without the deleted object.
